As the title states, I am a little rich. I was wondering if I should go one step hotter on the plugs or just run the platinum versions of the 7's and 9's. I am running the standard BUR7EQ and BUR9EQ plugs now. There aren't any idiot lights on, and it runs fine with the exception of fuel coming out the tail pipe. Any thoughts are greatly appreciated.

What kind of driving are you doing?

Running rich probably isn't due to having the wrong plugs. It's more likely due to misadjusted sensors, bad plug wires, bad plugs... etc. Last tuneup?

 

Check the FPR vac line.

It it blows off, you will run rich off boost & lean on boost.

BUR7EQP (L) platinums - for that longer lasting experience.

 

I drive the car hard at least for 5-10 minutes every time I take it out. My last tune up was when I got the car like 2 months ago, which included plugs, wires, air filter oil filter and change, along with an injector cleaner (Lucas).
